Pianoperformer: Alas, while I'm at a second-year level of competency, that doesn't mean I've only been practicing for two years! I've actually been doing it off and on through the years, probably altogether three or maybe even four years of lessons and practice -- so being able to "competently," if not particularly artistically, play (as opposed to "interpret") a piece like "Fuer Elise" is no big deal...nor an inspired few four-hour practice sessions in all those years!
And though not blind, all I do is memorize pieces, too -- no real sight-reading capabilities! But it's all just for fun, I really like the feeling of moving my fingers around like that (and one's whole body, too, when really getting into a piece). I am not currently taking any lessons, so it's honestly just a more dedicated kind of fooling around that I do! I guess I'm sort of debating right now whether to spend $2K on lessons for a year, or whether to spend it on an equally "useless" Wacom Cintinq 20WSX "touch screen" monitors for digital illustrations.
You're right about search engines liking constant updates, and not picking up on a site anyway for a few months (though I've only heard maybe up to three, not a whole half year!)...though some people report that being accepted for Adsense by Google results in being indexed by Google that much quicker.
I'm only putting forth a more fully-stocked site than not -- contrary to "best practices" advice on optimizing later -- because I envision my site being a kind of resource, and thus believe it should be "mostly usable" on launch (like a dictionary that's A-Z instead of only A-D while it takes time growing), though there will be plenty of "evolution" in terms of interactivity (I'm learning JavaScript and Python and plan on tackling PHP and maybe MySQL, too) to come. Plus there would be hard-goods to produce, an on-demand self-published book and DVD series...though those are even way off in the future, as in years ahead, since they require more learning and practice....
As for your tagline, I like it, though, if you don't mind my so saying, it's a bit of a commonplace idea, pushing past one's limits, expanding one's limits, etc. I do like it, but I can't say I love it, in the sense of the notion being particularly unusual. But it does work, don't get me wrong.
As for the different connotations between "stretch" and "transcend," Freshman Composition books on style usually advocate less Latinate words for more immediacy. Also, FWIW, to "stretch" can be thought of as a semantic subset of "transcend"...it really all depends on your own vision of its "soul"....
I think you have great potential for the blog, being that you are blind and yet not only program computers but play the piano (incidentally, the mental faculties involved may not be all that different as you seem to imagine, however; math and music are intimately related [see Douglas Hofstadter's "Goedel Escher Bach"], and more so than music and a visual art like painting). Perhaps a tagline referring more directly to that disability, even making up a word, like "multi-bility" --
www.multibility.com??...though that's not a tagline, but you see (uh, no pun intended) what I mean: what could be more a stretch or transcendence of limits in a tagline than making up a word?? That fits, of course....
Don't be impatient, though. It's gonna come to you. Believe that. Not on blind faith, but because you can recall similar instances in your life when everything just came together perfectly.
It'll happen. Just let it.
